HIS RIGHT TO CALVIN L. MAXWELL, OF PRINCETON, IOWA.

- IMPROVEMENT m LIQUID-MEASURES.

Specification forming part of Letters Patent No. 181,943, dated September 5,1876; application filed May 20, 1876.

To all whom it may concern:

Be it known that I, WILLIAM K. JOHN- STON, of Oordova, in the county of Rock Island and State of Illinois, have invented a new and valuable Improvement in Fluid-Measures; and I do hereby declare that the following is a full, clear, and exact description of p the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a central vertical section of my fluid-measure; and Figs. 2, 3, and 4 are detail views thereof.

This invention relates to devices for measuring liquids asthey are drawn from a reservoir; and it consists in a perforated rotating measuring-pipe, an air-passage, a spring for holding a rotating valve in place, and auxiliary devices, hereinafter particularly described and claimed.

In the annexed drawings, A designates a reservoir, from which the liquid is drawn. B designates the cover, to which is rigidly attached a projecting plate, I), which is perforated for the passage of an operating-rod, E,

and provided on its surface with pins b, or

their equivalents, which may be lugs or teeth or a notched rack-bar, for locking the rod E in any position desired. These pins should be arranged to indicate the standard liquidmeasures. 0 is a cylindrical casing or measuring-vessel, which is rigidly attached to the main vessel A, and which communicates with the interior thereof through a perforation, 0, below which is the horizontal partition 0 which is perforated for the passage of the hollow rodor measuring-tube E, and which supports the rotating plate or valve, hereinafter described. The partition 0 is also provided with a small hole, 0 designed to register with a similar hole in the rotating valve or plate. D is a sleeve, which envelops and protects the operating-rod or measuring-tube E, and is provided at itslower end with a cap, D, which constitutes the cover for easing O. Sleeve D is preferably left free at its upper extremity, or connected with plate I), and cap D is detachably connected by screw-threads, or in any equivalent manner, to the casing O.

The hollow operating-rod or measuringtube E is provided at the top with the-pivr. oted handle E, and bears the plate or rotating' valve 6, which is perforated at 0 and rests upon the partition 0 of the casing G. The hole 0 is adapted to register With the hole 0 in the partition 0.

Spring F, between cap D and valve e, holds the valve down upon the partition 0 A washer of soft material, suitably perforated, may be interposed between the 'valve 6 and the partition 0 to preserve the metallic surfaces from abrasion.

That part of hollow rod or measuring-tube E which is below the plate or valve is perfo-- rated at e 0 These holes are arranged at such heights as to discharge from the measuring-casing O the different liquid-measures, such as pints, quarts, &c. Said holes are also arranged at various points around the circumference of the tube.

G is a sleeve or outer tube, which is rigidly attached to a bottom piece, G, of easing G, which bottom piece is preferably made detachable, though water-tight. Sleeve G fits over the measuring-tube E, and is provided with holes 9 g 9, arranged above one another, and adapted to register with the holes in tube E. On the lower end of sleeve G is a tube and faucet, H.

The operation is as follows: Hollow rod or measuring-tube E is turned by handle E until hole 0 in partition registers with hole 6 in rotating plate or valve 0. The liquid will then flow down into the lower part of measuring-vessel 0. Then tube E is turned far enough to make one of the holes e which corresponds to the amount desired to be drawn, register with a similar hole in sleeve Gr. It is then only necessary to turn the cook or faucet, and the required quantity of liquid will flow out.

The rod E is made hollow, to allow the escape of air while liquid is being admitted into the measuring-receptacle O, and is carried up to the top of the receptacle, so as to avoid the possibility of the liquid overflowing. -I graduate plate I) on its upper surface to prevent mistakes.

What I claim as new, and desire to secure by Letters Patent, is-

' 1. The combination, substantially as hereinbefore described, of a perforated rotating measuring-pipe, an air-passage, and a spring for holding a rotating valvein position.

2. The combination of valve e with cap D,

sleeve 1), and spring F, substantially as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
